... So whilst in John Lewis, I had a look to see what else was available and found the Mitchum anti-perspirant deodorant that claims it is 'so effective you can even skip a day'. At the price of £1.77 it seemed worth trying.

in summer my problem isnt sweaty armpits but a very sweaty back. Can Mitcham help me?

I'm not sure if you're a user of Mitchum or not, however I use it on my armpits and chest, although not on my back, but I find it works rather well for me. Before I would have sweat patches from using brands such as Sure, but from using Mitchum this hasn't been a problem for me. One issue I have found however is that it can dry your skin out a bit, at least for me anyway. Perhaps you could try salt rocks instead? I've heard they work for sweat.

Yes of course you can spray this on your back and it should help with your sweaty back. However, if this brand of anti-perspirant does not work for you, you can always go down the root of a stronger anti-perspirant brands such as
Odaban Antiperspirant Spray, Anhydrol Forte Roll-on and Driclor. All can be applied to your back but you will need some help in application.
Hope this helps.

When it comes to mitchum I will be honest and tell you I don't have a clue if it will help your back but I have used it for under arms before and found it hasn't helped in the slightest. However, I have recently started to use Dove Anti perspirant and that has worked fantastically. It's non greasy, rubs in really easily and lasts up to 48 hours so may well be worth giving it a try.
